Multiple input filters fail in Paraview
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
A filter which accepts inputs
- vtkPolyData Can't be instantiated in the gui. When trying to, paraview segfaults if the highlighted dataset is of type vtkDataSet. When the highlit data is vtkPolyData is is sometimes possible to instantiate the filter. I've examined vtkGlyph3D and vtkPVGlyph filters to see how they cope, but it seems that things behave better when the input is a member of the glyphsources group. An example of a mutiple input filter that works would be very useful. I'd like to process heirarchical data, but paraview also crashes if I try to instantiate my filter with one of these selected.
The stack trace is so convoluted and long it's hard to follow the sequence of events leading to the crash. Always occurs in vtkkwutilites ln 646 Tk_PhotoHandle photo = Tk_FindPhoto(interp, const_cast<char *>(photo_name)); which is well away from the real trouble.
